Perhaps the better generic terms are UHF Male and UHF Female, but it

Or is it that they actively DISlike using the name "UHF"?
Ian,
Possibly. I assume that you are hinting at its performance from an
impedance discontinuity point of view... however IMHO the greatest
disadvantage of UHF connectors is also apparent at HF. UHF connectors
depend on proper alignment of the vee points and notches and the
coupling ring being very tight to provide ongoing reliable connection
that doesn't degrade with vibration.
"UHF" is a bit of a misnomer I agree, but it has market acceptance in
one of the largest market places, and that is the generic term for the
things.
On another note, I was a little surprised to see the mobile phone
manufacturers use the mini-UHF connector which inherited all the
faults of the UHF connectors earth / coupling ring arrangement.
Probably cheaper and a bit smaller than the TNC connector that they
appeared to have standardised upon at the time. Then Nokia needed to
invent a proprietary connector, all when SMA would have worked fine.
